Plokštinė was an underground missile base of the Soviet Union. This is the first nuclear missile base of the Soviet Union, an underground R-12 Dvinaballistic medium-range missile base. In 2012, the Cold War Museum was opened at the site.

At the time when the United States started building underground military bases, it was decided that the Soviet Union had to maintain its military advantage. Therefore, in September 1960, the Soviets started rapid construction of an underground military base, one of the first in the Soviet Union, near the village of Plokščiai. The chosen location was 160 metres above sea level and it could cover all of Europe, including Turkey and southern European countries. In 1960, more than 10,000 Soviet soldiers started secret works in the Žemaitija National Park that took two years. The costs of construction were comparable to the costs of building a city district or a small town.

The base was one of the top Soviet military secrets that was revealed by U.S. reconnaissance only in 1978. The base boasted of a network of tunnels and included four deep shafts that have a depth between 27 to 34 meters. They were covered by the concrete domes that could be moved aside on rails in 30 minutes. The base could stay autonomous for 15 days, or for 3 hours if also hermetically sealed. The surrounding electric fence was normally connected to 220 V, with a possibility to raise the voltage to 1700 in case of alert. The active team consisted of about 300 people, most of them military guards.

The base included four silos that housed R-12 Dvina missiles with nuclear warheads. These missiles were propelled using a medium-range liquid. They weighed more than 40 tones, including 1,500-kilogram warhead. These surface-to-surface missiles had a radius of a little less than 2,500 kilometres. No missiles, even for tests, were launched from the base.

After twelve years of operations, the site was shut down. Since the collapse of the Soviet Union, the site has been abandoned and not maintained. It has been visited by urban explorers, also suffered from numerous metal thefts. After the reconstruction in 2012, the former base site now hosts the Cold War Museum, opening one of the four existing silos for visitors.

This was my second time to the cold war museum and it was as interesting as the first time. You can visit the entire launching place. The exposition is very interesting and unique. I could recommend anyone interested in the cold war era to visit this museum. I'm sure I'm going there another time in the near future.

Even though some of the stuff has been taken out the bunker you can still feel the USSR presence in the bunker. Very nice museum to go to and a must see for all tourists. Handy audioguide in English as well as in russian. There is the possibility to guide yourself or go with a guide. Very friendly staff as well.

Interesting and, despite much of the controls and electronics have been stripped away, a very impressive piece of cold war history On a site, not larger than 50 x 70 meter, hidden in a beautiful landscape, the USSR built it's first secret nuclear launch site, with 4 rocket silos and all the necessary equipment, underground. After years of derelict it has now been turned into a museum, and you can get really into the belly of the beast, walking around the launch tube. Although most of the original equipment was removed, you get a good feel of what it was like in and on that base.

A very interesting place to visit. You can definitely feel the cold war era there. The museum consists of four missile silos each 30 meters deep (though can only visit one) and a bunker. The bunker was a command centre with all the necessary utilities in order to launch a nuclear missile. The exhibits in the museum are interesting and the guide was wonderful too.

Goseck Circle

The Goseck circle is a Neolithic circle structure. It may be the oldest and best known of the Circular Enclosures associated with the Central European Neolithic. It also may be one of the oldest Solar observatories in the world. It consists of a set of concentric ditches 75 metres across and two palisade rings containing gates in places aligned with sunrise and sunset on the solstice days.

Its construction is dated to c. 4900 BC, and it seems to have remained in use until 4600 BC. This corresponds to the transitional phase between the Neolithic Linear Pottery and Stroke-ornamented ware cultures. It is one of a larger group of so-called Circular Enclosures in the Elbe and Danube region, most of which show similar alignments.

Excavators also found the remains of what may have been ritual fires, animal and human bones, and a headless skeleton near the southeastern gate, that could be interpreted as traces of human sacrifice or specific burial ritual. There is no sign of fire or of other destruction, so why the site was abandoned is unknown. Later villagers built a defensive moat following the ditches of the old enclosure.

The Goseck ring is one of the best preserved and extensively investigated of the many similar structures built at around the same time. Traces of the original configuration reveal that the Goseck ring consisted of four concentric circles, a mound, a ditch, and two wooden palisades. The palisades had three sets of gates facing southeast, southwest, and north. At the winter solstice, observers at the center would have seen the sun rise and set through the southeast and southwest gates.

Archaeologists generally agree that Goseck circle was used for observation of the course of the Sun in the course of the solar year. Together with calendar calculations, it allowed coordinating an easily judged lunar calendar with the more demanding measurements of a solar calendar.
